10 Species of Tree Frogs in Oklahoma (Pictures)

You can find tree frogs on all continents except Antarctica, with at least 19 species in the United States. Their natural habitat is trees, forests, and near water bodies. Although well known for their tree-climbing abilities, not all tree frogs prefer hanging out on high branches above the ground. Nonetheless, they have a fascinating ability to jump and most species can change color depending on the temperature and their environment.

Oklahoma’s river drainage systems, bottomland hardwood forests, and bald cypress swamps offer great habitats for tree frogs to thrive. Read on to learn interesting facts about 10 tree frogs in Oklahoma and where you can find them.
